FLOUR-BOLT.

SPECIFICATION forming part of Letters Patent No. 391,281, dated October16, 1888.

Application filed .Tune 25, i337.

To all whom it may concern:

Be it known that I, CnarsTrAN N. SMITH, a citizen ofthe United States,residing at Dayton, in the county of Montgomery and State of Ohio,'haveinvented certain new and useful Improvements in Flour-Bolts; and I dodeclare the following to be a full, clear, and exact description of theinventiomsuch as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specication.

Figure l of the drawings is a side elevation of my improved bolt withthe outer casing removed and the boltingcloth J broken away. Fig. 2 is abroken vertical longitudinal section of both ends ofthe bolt. Fig. 3 isa front end View with outer casing partly broken away. Fig. 4 is atransverse section on line rv x, Fig. l. Fig. 5 is a rear end View; Fig.6, a detail perspective view of bolting-cloth J.

The invention relates to improvements in Hour-bolts, the object being tobolt on a continuously-moving inclined plane; and it consists in theconstruction and novel combination of parts, as hereinafter set forth.

Referring to the drawings by letter, A designates theV frame of themachine, including the casing and the legs or supports upon which thelatter rests. The actuating-shaft B isjournaled at the end that carriesthe pulley in the side of the casing and at the opposite end ina boss onthe end plate of the feed-conveyer casing or cylinder O, having thefced-openings c at its upper and outer end. The feed-eonveyer screw D issecured to a sleeve, d, secured to and turning with the shaft B withinthe casing or cylinder O.

E E are sprocket or pin wheels, preferably the latter, one secured tothe shaft B inside one end of the casing and the other provided with ahollow hub, c, that rides on the feedcylinder and is connected by radialarms with a smaller hub, e', secured to the shaft inside of the innerside of said cylinder.

F is an end board, upon the concave upper edge of which the hub c restsand turns, and with its edges converging downward. The end board hassecured to its outer side, at the edges thereof, the stripsf,wl1ich havesecured Serial No. 942,409. (No model.)

l between their upper ends a transverse board aiding in the support ofthe feed-conveyer cylinder.

G is a wheel below the corresponding pinwheel E, and journaled on a pin,g, secured to a slotted plate, H, rendered adjustable on a piece, h,fixed between the lower ends ol' the stripsf by means of the set-screwsh', asshown in Fig. 2. The said pin moves in a slotin the piece 7L, andwhen adjusted by the screws It is set or held by the screw h2, whichpasses through the upper edge of the piece h. The wheels E and G areconnectediby the band I, provided with the metal eyelets fi, thatregister with the pins on the upper wheels. At the opposite end ofthereel there are similar upper and lower wheels to those described,bearing similar letters, the upper wheel having been described, and thelower wheel being adjustable and set by similar parts bearing similarletters. There is no end board at this side which is open, except so faras itis closed by parts hereinafter described.

The two eyelet-strips I have their inner ends secured to thebolting-cloth J, which has its ends formed by said straps and has itsform re tained between the straps by the spring-bands K, which partakeof the general shape imparted to the cloth by the wheels E G and lieagainst the inner surface of the cloth in eircumferential pocketsforlned thereon by cloth or other suitable material, the pockets beingstitched at both edges to the cloth to retain the spring-bands in place.

L and M are respectively longitudinal eX- terior and interior strips,which are arranged in equidistant pairs, the members of each pair beingopposite and bolted together. The strips aid in keeping thebolting-cloth in its proper form.

Nis a wide longitudinal board running withinthe bolt, with its endssecured to proper points of the framework thereof. Standing inward fromsaid board N are the equidistant guideboards O, which have their outeredges pivoted about centrally to the board N and their inner edges free.These boards incline downward at such an angle that the upper edge ofany one is about or a little more than vertically above thelower edge ofthe adjacent one toward the feeding end ofthe machine. The

IOO

of the said handle the guide-boards O can4 have theirinclinationschanged to suit'the rate of speed required by the operator.

Vhen the material is fed into the feeding cylinder, it is conveyedthence through the open inner end of said cylinder within the bolt andfalls upon the rear surface of the boltingcloth, which is inclinedupwardly and rearwardly by means of the curved arms P upon alongitudinal shaft, p, pivoted in the ends of the frame and actuated bya suitable handle on its outer end. The said arms P bear against therear edges of the end portions of the reel proper. The shaft p has uponit a ratchetwheel, Q, which is engaged by a pawl, q, pivoted on the mainframe, so that the bolt can be held at any desired inclination withincertain limits. The flour rst falls upon the adjacent lower inclinedpart of the bolting-eloth, which is moved continuously upward by thedescribed mechanism and is moved upward therewith, the interior strips,M, acting somewhat as buckets. Vhen on the upper turn of the cloth, itfalls therefrom upon the adjacent guideboard O, down which it slides tothe bottom of the bolt a certain distance nearer the discharge endthereof. It is then again elevated, as before, and falls on a secondboard O. It progresses thus toward the discharge end of the bolt, thefine our passing through the bolt-cloth and,falling upon the inclinedsides R R of the casing, is delivered thereby into the conveyers S, ofordinary construction. All else than the bolted flour passes out throughthe discharge-chute T, lying against the last rear guide-board O. It isfound in practice that the spring-bands here` tofore described arerendered necessary to keep the bolting-eloth in proper forni.A Beforethe flour passes to the conveyer it falls on the guide-blocks T rI",which are triangular in cross-section and have their inclined sidesupward. By means of the said blocks the Hour may be delivered entirelyon one side in any desired quantity.

The lower Wheels, G, are notprovided with pins, as they will turn betterwithout the same.

'Ihe board N, to which the deectors O are pivoted, is secured in astationary manner to the frame, and as the bolt swings on the shaft Band is held at any angle by the ratchetwheel Q and pawl q it will beseen that by throwing the bolt to the left the face or edges of thedeflectors will come in contact with the longitudinal strips M, whichact as buckets.

Having described my invention, I claiml. In a tlour-bolt, thecombination of wheels E and G, bolting-cloth J, provided with pocketsand having its ends supported by said wheels, the circumferential springs K,secnred within said pockets, and means for imparting motion towheels E, and through them to the cloth, substantially as specified.

2. In a flour-bolt, the combination, with the main frame, the Wheels Eand G, and the boltingcloth provided with pockets, of the shaft p,journaled in the main frame the arms P and ratchet-wheel Q,seeured tosaid shaft, and the pawl q, pivoted on the frame for the pur pose ofholding the bolt at the inclination to which it has been turned by thearms, substantially as specified.

3. In a flour-bolt, the combination, with the bolting-eloth having thestraps secured to the ends thereof, provided with eyelets, and thepin-wheels on the main shaft, of the wheels G, `)'ournaled on Athe pinsg, the adjustable slotted plates H, the pieces h, and set-screws h',substantially as specified.

4. In a-i'our-bolt, the combination of wheels E and G, bolting-cloth J,provided with pockets and having its ends supported by said wheels,thecircumferential springs K, secured within said pockets, the longitudinalinterior and exterior strips bolted together, and means for impartingmotion to wheels E and through them to the cloth, substantially asspecified.

In testimony whereof I affix my signature in presence of two witnesses.
